What in the world are you doing?I'm 47 years old. Obviously I'm having a mid-life crisis.Have you ever wanted to do something but never got around to it? Maribeth had wanted to hike the Appalachian Trail ever since she was a kid. She waited almost four decades until the time was right. Hike along with her for over 2,000 miles through snow storms, heat waves, wildlife encounters and the scariest animal of all, her fellow man.She started hiking north from Georgia with a migration of thru-hikers all the way to New York State. Then, after taking the summer off to work, she started again, hiking south from Maine for a much more solitary experience on what is called a Flip Flop on the Appalachian Trail.
